Sweden Application March 14, 1949, Serial No. 81,253 In Sweden April 30, 1947 7 Claims.

The present invention relates to a device in such handles for door locks, particularly box locks, which are disposed on either side of the door and are attached to each other substantially in dependence on the thickness of the door. Usual locks of this type thus cannot be made completely ready for any doors, and therefore, when the lock is to be mounted in the door, a hole for a pm which holds the handles together has to be bored on the work place.

The present invention, on the other hand, relates to a device by means of which the lock is ready for mounting and the handles may be inserted in each other without any completing work and without regard to the thickness of the door.

For co-operation, the handles of such locks are connected by a longitudinally extended, partially square shaft bar provided in one handle and a recess having a cross section of the same shape as said shaft bar and serving as guide for same provided in the shaft portion of the other handle. The present invention is chiefly characterized in that the shaft bar is slotted or divided into two halves, the sides of which facing each other are spaced from each other at least over some distance, calculated from the free ends thereof, and are provided with a number of transverse hooks or teeth, the shaft portion of the other handle being provided with a member guided therein and shaped so as to engage the teeth of the two halves, by means of which member the handles, when displaced towards each other, are locked in desired position against the direction of displacement and are retained in this position.

A further object of the invention is a device for effecting a small displacement or fine adjustment between the handles without therefore reducing the size of the hooks or the secure hold thereof in the locking member.

The invention is illustrated in the annexed drawing which shows embodiments of the device according to the invention.

Fig. 1 shows a top view of a door lock placed in a door with the handles partly in section.

Fig. 2 shows a top view of the left handle shown in Fig. 1, in section and on a larger scale.

Fig. 3 is a top view on a larger scale of a part of the right handle shown in Fig. 1.

Fig. 4 is a top view on a larger scale of a part of the right handle shown in Fig. 1, giving another embodiment of the locking device.

Fig. 5 is a section, on a larger scale and viewed from the right, through the left handle in Fig.

1 along the line VV, with the embodiment shown in Fig. 4 adapted for the locking device.

Referring now to the drawing, 9 and I4 designate handles on either side of a door I5 provided with a box lock. The handle I 4 is provided with a longish shaft bar t, 5, which is square for a part of its length. The shaft portion of the other handle 9 has a recess 8 in which the bar 3, 5 fits and which serves as guide for same. The bar is slotted or divided into, two halves 4 and 5, the sides of which facing each other are spaced from each other along a shorter or longer distance, calculated from the free nds thereof and are provided with a number of transverse notches or teeth 6. The handle 9 is provided with a member I which is guided in the shaft portion thereof, said member having means 2 each of which are intended to grip behind one, arbitrary tooth 6 in the two halves 4 and 5, so that the handles 9, l4, when displaced towards each other, are locked against the direction of the displacement in a position determined by the thickness of the door, and are retained in this position. The engaging member consists of a bent plate spring I. The ends thereof are directed opposite to the direction of displacement of the handles 9, l4 like barbs and are causing a locking effect thereby that they take support against surfaces 1 arranged on the notches 6 and opposing the said direction of displacement. The plate spring I, 2 may be shaped as shown in Figs. 1, 2 and 3, viz. as a clamp with a medium portion 1 gripping around pin 3 traversing the handle 9 and with outwardly folded ends 2 forming the means in question which take support against the surfaces 1 of the notches 5. Another embodiment of the plate spring I, 2 is shown in Figs. 4 and 5. According to this, the plate spring I is shaped from a pin so as to enter hole Ill through the handle 9, with a bend shown in cross section approximately forming a semi-circle and with the ends 2' directed against the surfaces 1 of the notches 6 in order to serve as a locking member and make it fit for being driven out of the hole H], but in operative position being retained by resilient strain against the wall of said hole. The teeth 6 in the halves l, 5 of the bar are preferably saw-tooth-shaped with the teeth of the halves either placed with the points right in front of ach other (Fig. 4) or with the points so displaced relatively each other that the points of one half 4 (Fig. 3) will be disposed right opposite the spaces between the points of the other half 5 in order to reduce 3 the distance which the handles will have to be displaced for reaching the next locking position. A washer I2 is placed on either side of and close to the door as a stop against the handles.

The locking device for the handles shown in Figs. 1, 2 and 3 is so adapted, that the handles 9, [4 may be removed when the pin 3 has been driven out. The plate spring I, 2, however, remains in braced position between the teeth 6 in the bar halves 4 and when the handles are pulled apart. The device shown in Figs. 4 and 5, on the other hand, is so adapted that the plate spring 1', 2 can be driven out throughthe hole In. One end of the plate spring is so shaped that the spring, when necessary, may be extracted from the hole 10 by means of a tong or the like. In the first case, the handles 9, It may be removed and reinserted while the plate spring I, 2 all the time remains in the previously adjusted position.

As is evident from the above mentioned, the locking device connecting the handles may be adapted otherwise than disclosed in the specification and illustrated in the drawing without abandoning the principle of the invention.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A fixing device for handles arranged one on each side of a door, one of said handles having a shaft projecting therefrom the outer end of which is adapted for insertion into a recess in the other handle, said shaft including a slotted portion having confronting rows of teeth extending axially at said outer end, and means securing said other handle upon said shaft end comprising a plate sprin the opposite edges of which diverge outwardly and forwardly in the direction of insertion of said shaft end and engage said rows of teeth in the slotted portion thereof, said spring being carried by said other handle and fixed with respect thereto thereby to establish an interlocking action between said shaft and other handle preventing separation therebetween.
